Genetically modified food are a very controversial issue. On the one hand, we can make a lot of food in a small area, which is great for our expanding population. At the same time, genetically modified foods are creating “super-weed” since we can modify foods to resist weed growth, there are new strains of weeds that are resistant. Also, some genetically modified foods can lack nutrients, and not to mention they do not have to be labeled. You could be eating a genetically modified food right now.

How do molecules pass through the cell membrane ​
fiasKO [112]

Answer:

The small molecules such as water and carbon dioxide can easily or directly pass through the membrane because they are neutral and so small. the movement of water through the membrane is referred to as osmosis. water can also pass through the membrane through channel protiens called aquaporins (AQP).

Basic body color for horses is influenced by several genes, one of which has several different alleles. Two of these alleles— th
Phantasy [73]

Answer:

<h2>No,</h2><h2>Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute</h2>

Explanation:

 As given:

The chestnut (dark brown) allele and a diluting (pale cream) alleles show incomplete dominance, means that both the alleles in heterozygous condition show their effect. So the heterozygous show the phenotype which is intermediate of both the parents, here a horse heterozygous for these two alleles is a palomino.

 There is in fact, no particular allele present for palomino, this phenotype only results due  to having two  different alleles for a gene. So, palominos can never be pure-breeding because they can never be  homozygous.

Let P1 chestnut and P2  dilute,

Palomino is P1P2

The Punnett’s  Square for palomino mated to palomino:

P1P2×  P1P2

Gametes are: parent-1 P1 and  P2 , parent-2:  P 1  and P2

Progeny are:  P1P1,      P1P 2,    P 2 P1,    P2 P2

Genotypic Ratio: 1 P1P 1  : 2 P1P 2  : 1 P2P 2

Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute

which type of transport would be required for the solute molecules to move against the concetration gradient?
larisa [96]

Answer:

<u><em>Active Transport</em></u>

Explanation:

<u><em>active transport </em></u>

During <u><em>active transport</em></u>, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Which characteristic is used to classify galaxies?
Brut [27]
<h2>Answer:</h2>

The galaxies were classified based on the shape and structure exhibited by them.

<h2>Explanation:</h2>

In the 1920's, the galaxies were classified based upon the shape and structure by famous scientist Edwin Hubble. He did it by a telescope with which he captured various galaxies existing. He ordered (or "arranged") their shapes as winding, banned winding, curved, sporadic, and impossible to miss. This framework was known as the Hubble morphological succession of cosmic system types.  

Hubble noticed that a few universes, similar to the M31-Andromeda Galaxy, showed up as circles and had arms of stars and residue which showed up in a winding example. Like M31, these worlds showed up almost uniform in splendor. Likewise, Hubble saw that in a portion of these sorts of worlds the arms were all the more firmly twisted around the cosmic system. He called these winding systems. Our Galaxy, the Milky Way, is a case of a winding universe.
